tailieunhanh - Spinal Reconstruction Clinical Examples of Applied Basic Science, Biomechanics and Engineering

Spinal fusion remains at the center of many reconstructive procedures of the spine. However, several new concepts have recently emerged, which led many spine surgeons to rethink traditional approaches to common clinical problems. Examples of these new trends include use of artificial disc replacements for reconstruction of degenerated spinal segments instead of interbody fusion devices, percutaneous pedicle screw fixation systems instead of open screw placement, and minimal invasive decompressions through small percutaneously placed tubes instead of open, wide laminectomy procedures through large incisions. Minimally invasive techniques are now aided by computerized navigation systems; substitute, and expander materials are increasingly employed as adjuncts to autologous bone grafts; and growth factors,. | Spinal Reconstruction EDITED BY and Engineering Kai-Uwe Lewandrowski Michael J.
